MAX9140/MAX9141/ 40ns, Low-Power, 3V/5V, Rail-to-Rail MAX9142/MAX9144 Single-Supply Comparators General Description Features
The MAX9140/MAX9141 are single and the MAX9142/ ● Fast, 40ns Propagation Delay (10mV Overdrive) MAX9144 are dual/quad high-speed comparators optimized ● Low Power for systems powered from a 3V or 5V supply. The MAX9141 • 150μA Supply Current Per Comparator (3V) features latch enable and device shutdown. These devices ● Optimized for 3V and 5V Applications combine high speed, low power, and rail-to-rail inputs. ● Rail-to-Rail Input Voltage Range Propagation delay is 40ns, while supply current is only ● Low, 500μV Offset Voltage 150μA per comparator. ● Internal Hysteresis for Clean Switching ● Outputs Swing 300mV of Power Rails The input common-mode range of the devices extends beyond ● CMOS/TTL-Compatible Outputs both power-supply rails. The outputs pull to within 0.3V of ● Output Latch (MAX9141 Only) either supply rail without external pullup circuitry, making these ● Shutdown Function (MAX9141 Only) devices ideal for interface with both CMOS and TTL logic. All ● Available in SC70 and SOT23 Packages input and output pins can tolerate a continuous short-circuit ● AEC-Q100 Qualified (MAX9140AAXK/V+T Only) fault condition to either rail. Internal hysteresis ensures clean output switching, even with slow-moving input signals. The devices are higher-speed, lower-power, and lower- cost upgrades to industry-standard comparators MAX941/ MAX942/MAX944. The MAX9140 are offered in tiny 5-pin SC70 and SOT23 packages. The MAX9141 and MAX9142 are available in 8-pin SOT23 and SO packages, while the MAX9144 is available in both 14-pin SO and TSSOP packages.
Applications
